Abstract

Concrete used to join two prefabricated panels or like members is hardened by electric heating means which is removed once the concrete has hardened. The two members to be joined may be so positioned as to provide between them a cavity in which may be placed an element defining a chamber for the heating means, concrete being introduced around but not in said element.
